Class SurfaceZoomRegionList
- All Implemented Interfaces:
Iterable<ZoomRegion>
,Collection<ZoomRegion>
,List<ZoomRegion>
,SequencedCollection<ZoomRegion>
List of zoom regions for use with a
SurfacePlot
.
The number of elements changes according to the current state of the plot,
so don't copy it into an array and use that instead.- Since:

requestZoom
protected abstract void requestZoom(double[][] bounds) Invoked when the user indicates by mouse gestures that a zoomed view is wanted. The elements of thebounds
array are 2-elementdouble[]
arrays giving (lower, upper) bounds of the range along each axis which is required. A null element indicates that no zooming along that axis is required. Boundary values are in data coordinates.- Parameters:
